Offsetting Tailstock

The tailstock can be positioned offset from the spindle, or moved side-to-side from the spindle center line. This tailstock feature is most often used when cutting a taper. When the tailstock is positioned toward the operator from the center line, the machined workpiece end nearest the tailstock will be smaller in diameter than the end near the spindle. Conversely, position the tailstock away from the operator across the center line to machine a workpiece taper near the spindle.

Note: When using tailstock offset to cut tapers, you must use a center, faceplate, and lathe dog to mount the workpiece onto the spindle.

3.Re-tighten the lock screw to secure the off- set.

Note: To return the tailstock to the center line, repeat the process until the centered position is indicated on the offset scale.

Aligning Tailstock

The tailstock is aligned with the headstock at the factory. We recommend that you take the time to ensure that the tailstock is aligned to your own desired tolerances.

To align the tailstock with the headstock:

1.Using an machinist's precision level on the bedways, make sure the lathe is level side- to-side and front-to-back. If the lathe is not level, correct this condition before proceeding (refer to Assembly and Placement on Page 14 for detailed instructions).

2.Get two pieces of steel round stock, 2" in diameter by 6" long.
